Speaking of Numbers - Whoa!

Vodkapundit has a couple of interesting posts concerning the size of the crowd.

From his earlier post...
Here are some of the things she saw today, by the numbers.

•70 outdoor port-a-potties.

•90 minute wait to use one.

•The People Meter on Penn Ave had read 450,000 by noon, and 1.5 million two hours later. (That last number still looks awfully high to me.)

•1 DC police officer, who told her, “I’ve been here 20 years and this is the largest crowd I’ve ever seen.”
Then a follow up post...
Charlie Martin — a computer scientist with extensive intelligence experience — emails from his secret bunker near Boulder, CO:

I did a back-of-envelope based on the photos and reports. A pretty dense crowd is about 1.8 people per square meter, and the National Mall alone is about 125 hectares, 1.25 million square meters. So that would be 2.3 million people.

Given the report from Steve of an actual literal count of 450K early on, I think the 2 million number is *very* plausible.

Knowing Charlie like I do, I’m inclined to trust his guestimates more than most people’s “facts.”

Which in this case… whoa.
